Package dev.cel.runtime

Class CelRuntime.CelFunctionBinding

java.lang.Object

dev.cel.runtime.CelRuntime.CelFunctionBinding

Enclosing interface:

CelRuntime

@Immutable
public abstract static class CelRuntime.CelFunctionBinding
extends java.lang.Object

Binding consisting of an overload id, a Java-native argument signature, and an overload definition.

While the CEL function has a human-readable camelCase name, overload ids should use the following convention where all <type> names should be ASCII lower-cased. For types prefer the unparameterized simple name of time, or unqualified package name of any proto-based type:

• unary member function: _
• binary member function: __
• unary global function: _
• binary global function: __
• global function: ___

Examples: string_startsWith_string, mathMax_list, lessThan_money_money
